Abstract: A system has been developed at the U.S. Army Corps of Engineers Ohio River Division Geotechnical Engineering Laboratory using bar codes and a computer coupled balance to aid in data collection and reduction for conventional sieve analyses. This system has been extensively used in a production environment in the ORD lab, and has proven to save time in data collection, data reduction, and report preparation. Human errors in data recording are greatly reduced. The ability to immediately view and check the reasonableness of the gradation curve improves quality control. Currently, the bar code technology is being extended for sample identification at the ORD lab to allow the project and sample information to be automatically recorded as part of most test procedures.
